Integrative Review of Cobedding of Infant Twins.

ABSTRACT

OBJECTIVE: To synthesize the evidence on the benefits and risks of cobedding for infant twins and to assess the perceptions and practices of parents and health care workers regarding this practice. DATA SOURCES We searched the following databases for articles published between 1997 and 2022 CINAHL, Cochrane, Ovid MEDLINE, PubMed, Scopus, and Google Scholar. STUDY SELECTION We included full-text articles published in English in which the authors addressed twin cobedding in hospital or home settings. We reviewed the abstracts of 106 articles and retained 54 for full-text review. Of these, 18 met eligibility criteria and were included in the review. DATA EXTRACTION We extracted the following data author(s), year of publication, setting, purpose, study design, sample characteristics, methodologic details, outcomes and findings, and limitations. We appraised the quality of each study. DATA SYNTHESIS: In the included articles, researchers identified no differences in apnea, heart rate, or oxygen saturation between cobedded and separately bedded infants. Compared to separately bedded infants, cobedded infants had greater weight gain and synchronization of sleep-wake states. Researchers found benefits for procedural pain relief and recovery after heel lance among cobedded infants. Researchers report that many parents are choosing to cobed their twins, but we found limited qualitative data exploring parents' perceptions or practices. In the included articles, nurses had positive perceptions of twin cobedding. Overall, the quality of evidence was low because of inconsistencies in study methods and small sample sizes that resulted in imprecise results. CONCLUSION: We found potential benefits and no evidence of harm related to cobedding of twin infants. However, the evidence was insufficient to provide recommendations for practice, and additional research is warranted.
